Carnation plant named &#39;hilbechgre&#39;

ABSTRACT

A new and distinct cultivar of Carnation plant named ‘Hilbechgre’, characterized by its compact, uniformly mounding and upright to broadly spreading plant habit; relatively small leaves; freely flowering habit; light yellow-colored double flowers with red purple-colored margins and apices; and good container and garden performance.

Botanical designation: Dianthus caryophyllus.

Cultivar denomination: ‘HILBECHGRE’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Carnation plant, botanically known as Dianthus caryophyllus, grown commercially as a container plant, previously known by the name ‘Hilbchgrace’ and hereinafter referred to by the name ‘Hilbechgre’.

The new Carnation plant is a product of a planned breeding program conducted by the Inventor in De Kwakel, The Netherlands. The objective of the breeding program is to create new container Carnation plants with numerous attractive flowers.

The new Carnation plant originated from a cross-pollination made by the Inventor in De Kwakel, The Netherlands in April, 2012 of a proprietary selection of Dianthus caryophyllus identified as code number Fouta7626302, not patented, as the female, or seed, parent with a proprietary selection of Dianthus caryophyllus identified as code number A96166-10, not patented, as the male, or pollen, parent. The new Carnation plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in De Kwakel, The Netherlands in September, 2012.

Asexual reproduction of the new Carnation plant by terminal vegetative cuttings propagated in a controlled greenhouse environment in De Kwakel, The Netherlands since January, 2014 has shown that the unique features of this new Carnation plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Carnation have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Hilbechgre’. These characteristics in combination distinguish ‘Hilbechgre’ as a new and distinct Carnation plant:

-   -   1. Compact, uniformly mounding and upright to broadly spreading         plant habit.     -   2. Relatively small leaves.     -   3. Freely flowering habit.     -   4. Light yellow-colored double flowers with red purple-colored         margins and apices.     -   5. Good container and garden performance.

Plants of the new Carnation differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Carnation are more compact than plants of         the female parent selection.     -   2. Plants of the new Carnation and the female parent selection         differ in flower color as plants of the female parent selection         have pink-colored flowers.

Plants of the new Carnation differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Carnation have smaller flowers than plants         of the male parent selection.     -   2. Flowers of plants of the new Carnation are more fully double         than flowers of plants of the male parent selection.     -   3. Plants of the new Carnation and the male parent selection         differ in flower color as plants of the male parent selection         have white-colored flowers.

Plants of the new Carnation also can be compared to plants of Dianthus Caryophyllus ‘Hilbechbon’, not patented. In side-by-side comparisons, plants of the new Carnation differ primarily from plants of ‘Hilbechbon’ in flower color as plants of ‘Hilbechbon’ have dark yellow orange-colored flowers with pink-colored margins and apices.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Carnation plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Carnation plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Hilbechgre’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photograph and following observations and measurements were grown during the summer in 10.5-cm containers in a glass-covered greenhouse in De Kwakel, The Netherlands and under cultural practices typical of commercial container Carnation production. During the production of the plants, day temperatures ranged from 16° C. to 23° C. and night temperatures ranged from 13° C. to 18° C. Plants used for the photograph and description were 13 weeks from planting and were pinched one time at the time of planting. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
